[Objective] The objective of this paper is to study the allelopathy effects of hyperaccumulator straw on heavy metal accumulation of accumulator in order to provide basis for the study of phytoremediation of cadmium-contaminated soil.[Methods] By applying different straws of hyperaccumulators(Youngia erythrocarpa, Bidens pilosa, Solanum photeinocarpum and Siegesbeckia orientalis) in cadmium contaminated soil, the effects of hyperaccumulator straw on growth and cadmium accumulation of Capsella bursa-pastoris were studied.[Results] The above-ground biomass, total biomass, resistance coefficient and leaf SPAD(soil and plant analyzer development) value of C. bursa-pastoris was increased by applying four Cd-hyperaccumulators straws in soil, compared with the control treatment. By applying straw of Y. erythrocarpa in soil, the cadmium contents in root, stem, leaf and above-ground part of C. bursa-pastoris were increased by 11.81%, 102.07%, 12.00% and 54.95%, respectively, compared with the control treatment. The available cadmium concentration in soil was also increased. By applying the straws of B. pilosa, S. photeinocarpum and S. orientalis in soil, cadmium content in C. bursa-pastoris was decreased. By applying straw of Y. erythrocarpa in soil, the cadmium accumulation in above-ground part and whole plant of C. bursa-pastoris was 42.11 and 54.74μg/plant, which was 83.09% and 54.11% greater than that in the control treatment, respectively. By applying the straws of B. pilosa, S. photeinocarpum and S. orientalis in soil, cadmium accumulation in C. bursa-pastoris was decreased.[Conclusion] Applying the straw of Y. erythrocarpa in soil can improve the cadmium accumulation of C. bursa-pastoris, which is beneficial to the remediation of soil contaminated by cadmium.
